1975-1986 C10 LS Swap Kit Level 1, 4L60E/6L80 Automatic (SE1-C107586-LSX-A1)

Description

This Holley Swap Essentials Level 1 kit is the mounting package for putting a GM Gen III/IV LS engine in 1975-1986 GM C10 two-wheel-drive trucks. It bundles the engine brackets, clamshell engine mounts with polyurethane inserts, through-bolt hardware, transmission crossmember and polyurethane transmission mount, matched for a 4L60E or 6L80 automatic transmission.

Holley designed the mounts in CAD to set the driveline angles, which cuts vibration and helps put the power to the ground. The engine position leaves room to route a dual exhaust up to 3 inches, and the black polyurethane inserts twist less than factory rubber mounts.
